 Found this on the web (Wikipedia).=C2=A0 Don't know if it is accurate or n=
ot but it is a Lucas chart so who knows!

Lucas type[edit]

Lucas=C2=A0type fuses are used in old British-made or assembled automobiles=
. The physical length of the Lucas ceramic type of fuse is either 1 inch or=
 1.25 inch, with conical ends. Lucas Glass tube fuses have straight ends. L=
ucas type fuses usually use the same color-coding for the rated current. Lu=
cas fuses have three ratings; the continuous current they are designed to c=
arry, the instantaneous current at which they will fuse, and the continuous=
 current at which they will also fuse. The figure found on Lucas fuses is t=
he continuous fusing current which is twice the continuous ampere rating th=
at the system should be using; this can be a source of confusion when repla=
cing Lucas fuses with non Lucas fuses. The Lucas 1/4" diameter glass tube f=
use have a different length as compared to the standard US item. The Lucas =
1/4" diameter glass tube fuse is 1 and 5/32" [=E2=89=8829.4=C2=A0mm] long, =
while the US standard 1/4" glass tube fuse is 1 and 1/4" [=E2=89=8832.0=C2=
=A0mm] long. However many Lucas fuse holders permit the longer U.S. version=
 to be installed easily.
